I've done every problem in this assignment so far. This one has me stumped though. Do I add the x to the half x? Or do I multiply by the reciprocal and then add the x?

You can add the two terms up first if you want. Or multiply everything by the denominator first if you want. Either is a valid thing to do, and either is a step toward the right answer. Just pick one and go for it.

Either works, but if I recall correctly the textbook-cookbook method is to combine like terms first. That means add the x to the 1/2x to get 3/2x.

This is a problem with any complications, no 'trick', so do it the way you were taught in class, otherwise a bad teacher will take off for doing things that are perfectly valid, but not the way you 'should' do it.

-10=(1/2) * X + X

-10=(3/2) * X

-10 * (2/3) = X

X =-2 * 10/3 = -20/3 = -6 * 2 = 6.6666666......

2/3 (-10) = x

it's about 6.5
